l?) all r11/0m zit 77ml/ concern: `Beitknownthat LFRANCis JOSEPH Fnnnsn, of Lowell, in the State of Massachusetts, but ftemporarilyresiding in the city of Montreal, 5 Pro-vince ofQuebec, Canada, have invented certain new and useful Improvements in Tires; and l-do hereby declare that the following is a full, clear, and exact description of the same. xo My invention relates tothe class of tires described and illustra-ted in Letters Patent of `the United States of America granted tome on the 16th O f July, 1305, under No. 542,678, forimprovements in Wheels; and it has for its scribed so that it can be removably attached to the rim of anywlieel, and, secondly, to inprove the construction thereof.

For full comprehension. of the invention zo reference must be'had to the accompanying drawings, forming apart of this speciiica' tion, in Whichlike symbols indicate-the same parts, andwherein.- I

Figure liis a side elevation, partly in secz 5 tion, of a Wheelfitted Withatire constructed according to my present invention; Fig. 2, a transverse vertical sectional` View thereof, taken on line 2 2, Fig. l; Fig. 3, a similar view to Fig. 2, but showing the tire inits extended 3o state as it appears before being compressed to be set on the rim of the wheel; and Fig. 4 is a similar View to Fig.2, showing the tire compressed.

The hub a, spokes b, and rim c do not form shown being only for purposes of illustration, as-my tire can be applied to any of the wellknown Wheels at present in use.

My improved tire consists, preferably, of 4o inner and Outer rings (lettered d and c, re-

spectively) composed of resilient materiah' preferably steel, the inner ring d `being open and having its ends CZ d2 overlapping each other, and the edges d3 of each'ring are turnedV 45 inward .toward each other, as shown in Fig..

1, and a series of projections f, pressed radially therefrom, arranged and spaced so that the project-ions Vfrom each ring will be diametiicalliY opposite the projections of the 5o other. 'Each pair ci these projections f, situated opposite te one another, are adapted 'to together.

seni no. 565,282. (No mais) act as guides for a coiled spring f, and these several' parts can be held in their positions r reitive to each other by any usual and well` known forni of tirc-coii'ering, but i prefer to 55 use a covering of peculiar formation.

`lily improved covering, which is particularly adapted to my present forni of tire,.eon sists cfa thick Woven or textile central portion 71 diminished in thickness from its cen- 6o ter toward its sides, and forms the tread and the lower. portions of the sides of the tire, and an elastic portion h on each side of .and

cemented or otherwise connected to such textile central portion h, and the textile and 65 elast-ic portions together being of sufficient Width to encircle the tivo rings Z and c and springs h and have the edges overlap each otherV in order that they may be connected 'Vhen this is done, the tire will 7o be complete and it will only be necessary to compress the springs through'the inner ring, which, beingnopen, will expand and allow of the compression of all the springs at once sufficiently' to place the tire around the rim 7 5 of a `wheel, when, upon their being released, they Will naturally expand and cause the tire to grip the` rim and thus be held iirmly in place. p

A covering of an even-thickness through- 8o out or one composed entirely of rubber can be substituted for the one described, or blocks of rubber for the springs g, or the construe tion, arrangement, and 'combination of the parts changed, without departing in any Way 85 from the spirit of my invention.

lVhat I claim is as follows:

1. A Wheel-tire composed of an inner open ring, anouter intact flexible ring, a series of yielding resistances located between such in- 9o ner and outer rings and a iiexible covering for thewhole, for the purposeset forth.

2. A wheel-tire composed of an inner open "ring-and an outer intact flexible ring, each ring being formed with a series of'guides, a 95 series of coiled springs having their ends located about such guides, and a flexible covering for the Whole, for the purpose set forth.

3. A wheel-tire composed of an inner open ring, and an outer intact flexible ring, each roo ring being formed with a series of guides formed in one therewith, a series of coiled springs having their ends located about such guides, and a flexible covering for the whole, for the purpose set forth. l

4. A wheel-tire composed of an inner open ring, an outer intact llexible ring,a series of yielding resistanees located between such in- 11er and outer rings and 'a flexible covering for thewhole formed Woven material and p t'e'ril, forV the 'purpose 5. A whee1-tire composed of an inner open ring, and an outer int act flexible ring, each guides, 'and a flexible covering ring being formed with a series of guides formed in one therewith, a series of coiled springs having their ends located about such I5 for the Whole formed partially of textile or Wovenniaterial and partially of elastic material, for the purpose set forth.
